AI summary The evidence provided by Colin T. Fitzhenry and Michael P. Gorman critiques NS Power's proposed ELID Tariff design, arguing that it is imbalanced and over-charges PHP. They recommend that the ELID Tariff should include a capacity charge for firm demand service and recover non-firm power supply costs through the energy charge.

- 4 NS Power's proposed design of the ELID does not reasonably reflect the 5 firm and interruptible service provided to PHP under the proposed ELID 6 Tariff. PHP does not support the Company's ELID rate design. If the Board 7 prefers NS Po...

AI summary PHP objects to NS Power's proposed ELID rate design, arguing it does not reflect the actual service provided and results in over-recovery. PHP recommends adjusting the design to reflect NS Power's cost of service and align the tariff with updated energy sales forecasts for accuracy.

15 Q HOW WILL NS POWER PROPOSE TO PASS ON THE BENEFITS OF THE DR AND 16 INTERRUPTIBLE SERVICE TO PHP? 17 A There will be two credits made to PHP cost of service. First, NS Power will provide a 18 billing determinant demand charge credit eq...

AI summary NS Power proposes passing benefits of DR and interruptible service to PHP via two credits: a demand charge credit (matching LIIR interruptible rates plus a 10% premium) and a power supply credit based on modeled savings from dispatching PHP load during high-cost periods. This reduces NS Power's supply costs, benefiting PHP while maintaining costs for ATL customers.

17 Q DOES NS POWER RECOVER PORTIONS OF ITS GENERATING RESOURCE 18 COST THROUGH THE ELID ENERGY CHARGE? 19 A Yes. NS Power uses a System Load Factor ("SLF") methodology to functionally allocate generating resource cost to demand and energy....

AI summary NS Power uses a System Load Factor (SLF) methodology to allocate generating resource costs to demand and energy under the ELID Tariff. This approach applies uniformly to all generation assets, allowing PHP to support cost recovery of a significant portion of generating resource costs through the ELID energy charge.

III. Assessment of the Energy Charge - Q. Please summarize the ELID Energy Charge proposed in NSPI's application. - A. NSPI proposes an Energy Charge of 9.977 ¢/kWh in 2026 and 11.240 ¢/kWh in 2027. 52 - Q. How were the Energy Charge rates...

AI summary NSPI proposes ELID Energy Charges of 9.977 ¢/kWh (2026) and 11.240 ¢/kWh (2027), calculated via a cost-of-service study (COSS) that treats PHP as an ATL customer. The rates incorporate fixed costs and net PHP load after subtracting Goose Harbour output (507 GWh), reducing PHP's modeled load to 304 GWh. This lowers PHP's total payments but increases per-kWh charges due to fixed cost allocation.

Q. What is the effect of PHP net load being too low in the COSS? - A. In most direct terms, if PHP's net load in 2027 subject to the Energy Charge is 121 GWh rather - than 304 GWh, a 60% reduction, the revenue from PHP to NSPI would be low...

AI summary A lower PHP net load in the COSS reduces NSPI's revenue by ~$21M (60% reduction) and increases ELID Energy Charge rates due to fixed costs not scaling with energy use. This risks under-contributing to system costs, shifting burdens to other FAM customers. NSPI's application uses an inflated PHP net load, leading to undervalued Energy Charge rates.
